Specification of Letters Patent.

Application filed September 27, 1911.

Serial No. 651,661.

To all whom it may concern Be it'known that I, HOWARD S. GARDNER,

a citizen of the United States, residing at East Orange, in the countyof Essex and State of New Jersey, have invented certain new and usefulImprovements in Conveyer- Hoppers; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill onable others skilled in the art to which it appertains to make anduse the same.

This invention relates to conveying apparatus provided with an endlesscable and flights, and adapted to raise concrete material to the topfioor of a high building in course of construction; and it consists of ahopper adapted to be connected to the conveyer pipe and arranged ashereinafter fully described and claimed.

In the drawings, Figure 1 is a vertical section through the lower partof a conveyer provided with a hopper according to this invention. Fig. 2is a cross-section through the hopper, taken on the line wm in Fig. 1.Fig. 3 is a vertical section through the hopper, taken on the line yg inFig. 2.

A casing or trough 2 is arranged on the ground floor of the building,and 3 is a shaft journaled in the casing and provided with a drivingwheel or a guide wheel 4. An endless conveyer cable 5 is provided andhas conveyer flights 6 of approved construction secured upon it. Thiscable works over the wheel 1 and over a similar wheel at the top of thebuilding which is not shown in the drawings, and the conveyer may bedriven from the top wheel or the bottom wheel as preferred.

The conveyer cable is driven in the direction of the arrow in Fig. 1,and its ascending stretch passes through a conveyer pipe 8 which extendsthrough the various floors of the building, and which is preferablyformed in sect-ions of suitable length.

In order that the action of the wheel 4 may not be impeded by theconcrete material, which is usually delivered into the casing or trough2, the conveyer pipe is provided with an inlet opening 9 in one side ofit a little above the casing 2. A

rectangular hopper 10 is provided having converging portions 11 on oneside and an opening 12 between these converging portions. This hopperhas also curved flanges 13 at its top and bottom. The opening 12 isarranged over the opening 9 in the conveyer pipe, and 14: are clampingbands provided with bolts 15 which clamp the flanges against theconveyer pipe and secure the hopper in position. A feed trough 16 forthe mixed materials is connected to the upper part of the hopper, and 17is a spiral conveyer which works in the trough 16. A guide wheel orroller 18 is journaled on a pin 19 and is arranged at the upper part ofthe openings 9 and 12 so that a portion of its periphery projects intothe said openings. This wheel or roller prevents the conveyer flights orlumps of material from catching against the top edges of the saidopenings. The hopper 10 is arranged to extend above the level of thetops of the openings so that the material is fed through the saidopenings in a satisfactory manner, The hopper can be removed andreplaced whenever desired, and the opening in the pipe can be closed andthe material fed into the casing 2 whenever desired. The concretematerials are preferably mixed in dry form in a mixing machine of anyapproved construction to which the spiral conveyer 17 and its feedtrough are connected.

The concrete materials are conveyed through the conveyer tube to the topof the building, where they are mixed with the necessary water, and arethen distributed to the various floors of the building, as required foruse, in any approved manner. The conveyer can be used for any othermaterials besides concrete materials.

What I claim is:

1. The combination, with a tubular conveyer pipe having a feed openingon one side, and an endless cable provided with flights for elevatingthe material in the said pipe; of a removable feed hopper open on oneside and provided with flanges for hearing against the said pipe, andclamping devices for securing the hopper to the pipe over its said feedopening.

2. The combination, with a conveyer pipe having an opening inyone side,and an end- In testimony whereof I have afiixed my less cable providedwith flights for elevatsignature in the presence of two witnesses. ingthe material in the said pipe; of'a feed hopper for the material securedto the said HOWARD G 5 pipe over the said opening, and a I guideWitnesses:
